What is the slope and y-intercept represented in the table?

slope: $$\frac{1}{2}$$ , y-intercept: 7

slope: $$-\frac{1}{2}$$ , y-intercept: 0

How do you find the rate of change or slope when you are given a table?

Choose 2 ordered pairs, then use the formula $$m=\frac{y_2-y_1}{x_2-x_1}$$

Find out the y-value when the x-value is 0

Choose 2 ordered pairs, then use the formula $$m=\frac{x_2-x_1}{y_2-y_1}$$

Add all the numbers up and divide by the number of numbers

If you are given a table, and the table shows you the x-value of 0, how do you find the y-intercept from the table?

If you know the x-value is 0, then the y-intercept is the y-value that goes with the x-value of 0.

There is no way to find a y-intercept from a table

The y-intercept is the all the y-values averaged together

The y-intercept is the difference between the largest y-value and the smallest y-value

If you are given a table and it DOES NOT show you the x-value of 0, how do you find the y-intercept from the table?

First, find the slope of the line using the slope formula, then using the formula y=mx+b, substitute in the slope for m, an ordered pair from the table for x and y, and solve for b.

The y-intercept is all the y-values averaged together

Look at the graph. Which best represents the y-intercept of the line shown in the graph?

After 0 minutes, $$2\frac{1}{3}$$ miles have been traveled

After 0 minutes, 0 miles have been traveled

After 0 minutes, $$\frac{2}{3}$$ miles have been traveled

After 0 minutes, $$\frac{3}{2}$$ miles have been traveled

Which of the following shows the slope and y-intercept of the graph?

Slope = $$-\frac{1}{2}$$ ; y-intercept = -6

Slope = $$\frac{1}{2}$$ ; y-intercept = 6
